Preheat your oven to 320°F (160°C). Take your prepared Keto Heavy Cream Bread and cut it into 10–12 slices, then cut each slice into uniform bite sized cubes.
Place the bread cubes into a large mixing bowl. Pour the olive oil over the bread generously, then sprinkle in the salt, black pepper, and oregano.
Toss the cubes gently until every piece is evenly coated with the oil and seasoning. Spread the cubes out in a single layer on a baking sheet (use parchment paper for easy cleanup).
Bake for 30 to 35 minutes. You must stir and flip the croutons every 5 to 10 minutes to ensure they brown evenly on all sides without burning.
Remove the tray from the oven. Let the croutons sit and cool for at least 15 minutes before serving.
